Letters Patent No. 82,602, dated September 29, 1868.

IMPROVEMENT IN CHAIRS.

TO ALL WHOM, IT MAY CONCERN:

Be it known. that I, DANIEL C. OOLBY, of the city of Washington, District of Columbia, have invented' new and useful Improvements in Cane-Seat Chairsjand I'do hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompany and form a part of these specifi-- cations, in which- Figure 1 is a plan view of a chair-seat with my invention applied.

Figure 2, sectional views, one showing a. cord, the other a flat strip, as an elastic rest for the cane-strands, each one resting in a groove adapted to it. y

Figure 3, sectional views, showing the manner of-attaching the rests to the upper inner edge ofthe seat-frame.

Figure 4, view of still'diiereut form of these rests.

Letter A represents lthe front of the seat-frame. f

Letter B, the two sides thereof, right and left.

Letter C, the cane-strands interwoven. i

Letters D D D D', the elastic rests, varying in form to correspond to the slight variations in the manner of applying them. i Y

Letter E, groove, in which the rjest D is placed, and may be seen in the sectional views of iig. 2.

The object of my -inv'ention is to provide an elastic or slightly-yielding rest forthe strands of a cane-seat, chair bottom, that 'they may not he prematurely broken across the inner upper edges of the pieces forming the s eat-f ram e. '4

The substance I use for these rests may be of textile fabric, felt, paper, leather, suitable preparations of rubber, or any other material affording the desired properties, so as to supply an easy and gentle rest for the cane-strands. Y I

The form may be cord, or. strips, as represented in iig. 2, or, as in g. 3, witha dat plane surface resting in the wood ofthe seatppresenting an upward surface, more or less oval, or it may be madeto clasp the cornel` of inner upper edge of the seat-frame, or any other convenient form, that may be comely in appearance, and have the qualities desired. l I i The application of these restsis just i-nsidethe holesvthrough the seat-frame, which receive the cane-strands, and may be by groove E, as in fig. 2, or be glued or otherwise attached to the surface on which they rest.

When the grooveE is used, it will be cut by ya tool for the purpose, guided by therow of strand-holes previously bored, and this groove, in either form shown in iig. 2, will be amply sufficient to keep the rest D in place.

If thought proper, however, when the form ofgroove shown in the lower section of fig. 2 is u sed, a little glue may be put in it and the strip D pressed i'n.

There is4 an advantage in usingthe form represented inthe upper section of iig. 2, as the'cord D is very easily and readily slipped into its place after the cane-seat is woven in.

The great advantage of this appliance of mine has been well demonstrated by use and trial, both in my house and oilice, where chairs thus supplied haveibeen in vconstant use,l together with others not thus supplied, though in all other respects the same, and these latter have required new bottoms, while those improved by the above-described device are apparently as perfect and durable as on the first day of their use.

I do not claim elastic cushions of rubber or other material as applied to upholstered` chairs to give fulness, but only as applied to cane-seats, that they maynot faihof goed condition in such very shogt time as most cancseats do when applied as has been the practice heretofore.

What I claim as 'of my invention, and desire to secure by Letters Patentgis- The application to cane-seat chairs of an elastic or sliglitly-yieldingl rest for the cane-strands, of any suitable mutcrial, and for the purposes specified and set forth.

In testimony whereof, I have signed my naine to this specification in the presence of two subscribing witnesses.
